Remove key from ignition switch and
turn steering wheel until it engages.
Retained power off The following electronic systems areoperable until the driver's door is
opened or at the latest for ten minutes
after the ignition is switched off:
● power windows
● power outlets
● power sunroof
Starting the engineTurn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Manual transmission automated:
operate brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn key briefly to position 3 and
release: an automatic procedure operates the starter after a brief
delay, until the engine is running. See
'Automatic Starter Control'.
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Driving and operating153Fault
If there is a fault in the system, the control indicator b illuminates
continuously and a message or a
warning code appears in the Driver
Information Centre. The system is not operational.
Have the cause of the fault remedied
by a workshop.
City mode City mode is a feature which enables
increased steering assistance during
lower speed conditions, e.g. city
traffic or parking. Steering assistance
is increased for greater convenience.Activation
Press B when engine is running. The
system works from standstill up to
35 km/h, and also in reverse gear. Above this speed, the system
changes to normal mode. When
activated, City mode engages
automatically below 35 km/h.
An illuminated LED in the City mode
button indicates that the system is
active and a message pops-up in the
Driver Information Centre.
City mode remains active during an
Autostop, but is only operational when the engine is running.
Stop-start system 3 136.
Deactivation
Press B; LED in the button
extinguishes and a message pops-up in the Driver Information Centre.
Each time the engine is started, City
mode is deactivated.
Fault
In the event of a fault in the system,
control indicator c illuminates and a
message is displayed in the Driver
Information Centre.
Vehicle messages 3 103.
System calibration
If control indicators c and b
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel
for one rotation with ignition switched
Driving and operating185Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricatethe coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg a speed of 80 km/h must not
be exceeded; the use of a stabiliser is
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 253.Trailer towing
Trailer loadsThe permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12%
The permitted trailer loads apply up to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than
8%, e.g. motorways).
Driving and operating1899Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Insert the key in the lock and unlock
the coupling ball bar.
Push the rotary knob onto the
coupling ball bar and rotate right while pressed down until it engages. Pull
out the ball bar downwards.
Insert sealing plug in opening for
coupling ball bar. Fold away socket.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 152.
